I am using this java code to produce output of amicable numbers...it compiles but when i run it, an error occurs in my terminal window and say "Exception in thread "main" java.lang.nosuchmethoderror: main press any key to continue...

also i need to add a joptionpane to my code, so i can tell the program what the upper bounds is for it to search upto certain amicable numbers is.
-----------------------------------------------------------------------
This is my Code

Code:

import java.util.*;
public class AmicablePairs{
	protected static Vector<Integer> getFactors(int number){
		Vector<Integer> result = new Vector<Integer>();
		for (int i = 1 ; i < number; i++){
			if (number % i == 0) result.add(new Integer(i));
		}
		return result;
	}
	protected static int sumNumbers(Vector<Integer> numbers){
		int result = 0;
		for (Integer integer : numbers)
			result += integer;
		return result;
	}
	protected static void printNumbers(Vector<Integer> numbers){
		for (Integer integer : numbers)
			System.out.println(integer);
		System.out.println();
	}

	public AmicablePairs(int bound){
		for (int m = 2; m <= bound; m++){
			for (int n = 2; n <= bound; n++){
				if (
				    (sumNumbers(getFactors(m)) == n) &&
				    (sumNumbers(getFactors(n)) == m))
				{
					System.out.println(m + ", " + n);
				}
			}
		}
	}
}
